3D Categorized Plots - Advanced Tab

Graphical Analytic Techniques

Select the Advanced tab of the 3D Categorized Plots Startup Panel to access the options described here.

Layout. Select the type of layout for the graph(s).

Separate

Select this option button to produce a Separate plot layout (where each subset of cases is displayed in a separate graph) for the categorized plots.

Overlaid

Select this option button to produce an Overlaid plot layout (where all subsets are overlaid in one graph and identified by patterns and colors) for the categorized plots.

Graph Type

Select the type of plot from the Graph Type list on this tab. Click the desired plot link below for a brief description of that type of graph.

Scatterplot	Surface
Space Plot	Contour/Lines
Spectral Plot	Contour/Areas
Deviation Plot

Variables

Click the Variables button to display a standard variable selection dialog box, in which you can select the x-, y-, and z-axis variables as well as the grouping variable to be categorized for the graph. The selection made will be displayed below the Variables button. Note that the selected grouping variable does not have to be a categorical variable (e.g., contain codes); you can use one of the methods of categorization options in the Intervals group box to categorize a continuous variable. (The grouping variable is not necessary if the categories are defined via the Multiple subsets method.)

Intervals

Use the options in this group box to choose a method of categorization of the values in the selected grouping variable. Each of the methods is discussed in the Method of categorization topic.

Fit

You can fit one of several equations to the data or use one of the data smoothing procedures in the 3D categorized plot by selecting one of the predefined functions on this list. Note that if a fit option is not available for the selected graph type, the only available option in this list box will be Off.

Linear	Neg Expon Weighted LS
Quadratic	Spline
Distance Weighted LS	Wafer

Deviation

Use this box (applicable to Deviation and Space plots) to specify a value on the z-axis that determines the level from which deviations are derived; or in the case of Space Plots, this value determines the Z-level of the X-Y plane.

No of Planes

This box is only available if you have selected Spectral Plot as the Graph Type. Use the No of Planes box to specify the number of spectral planes into which the data are segmented (compressed).

Statistics

You can include the multiple correlation in the footnote of the graph by selecting the Multiple r(z/xy) check box.
